Erica’s Notes

Corn is a heat-loving summer crop that needs gobs of fertility,┬ábut otherwise it’s not particularly picky. Although typically direct sown, corn transplants easily and,┬ásince it will grow at lower temperatures than it will germinate, starting corn seedlings under lights can move your corn harvest up by several weeks or a month.

One drawback to starting corn under lights is that you need a block of at least 16 corn plants for reasonable pollination, and more is better. That many corn plants take – at minimum – half a tray of space all by themselves, so if your space to start crops is limited, I’d pass on corn.

If you want to get a 3 or 4 week head-start on the harvest, plant two or three corn seeds per pot in deep, 2 or 3 inch pots. Set on a heat mat until you see strong germination. I wait to thin my corn until after I transplant out, usually sometime in May.
